Welcome to the Moms Panel, Karla! Thanks for stopping by with this excellent question!
Sounds as though you will be traveling alone with your 4-year-old and 6-month-old, However, let me reassure you that there are relatively few
attractions that only accommodate two people in a row. Even in that situation, the three of you should be able to ride most of them together. Many ride vehicles for attractions, such as, Under the Sea ~ Journey of The Little Mermaid, should easily accommodate you and both of your children. Others, such as, "it's a small world", offer bench type seating which will allow you to sit next to your 4-year-old while holding your 6-month-old on your lap. For rides such as Dumbo the Flying Elephant and The Many Adventures of Winnie the Pooh, the three of you will easily fit in one ride vehicle too.
Since you will be traveling alone, you won't be able to make use of
Rider Switch, unless another adult is present. Therefore, if you wish to experience some thrill rides too, consider using Kid's Nite Out. This is a Childcare Services agency that helps Guests in your situation. Their highly trained care providers will lend a helping hand with In-Park Assistance, accompanying you and your children to the theme parks. If you wish to have the same care worker escort your family to the parks for the duration of the trip, be sure to note this request when making the reservation. To learn more about their services, peek at their website www.kidsniteout.com, or contact Kid's Nite Out directly by calling (407) 828-0920 between 8:00 a.m. to 9:00 p.m., 7 days a week.
I hope you found this information useful, Karla. Please come back soon with more Disney vacation planning questions.
Wishing you a most memorable visit to Walt Disney World Resort!
